JLC JLC47BC3002 Television (47"): JVC SI50UR: Sound but No Picture - Vertical Lines & Tape Fix Attempt

Thu, 16 Apr 2026 04:53:04 -0700

My JVC TV (Model SI50UR) has sound but no picture; it only displays vertical lines. I already tried the DIY trick of placing tape on the flex cable pins, but that only changed the pattern of the lines. Also, when masking certain areas, the lines react to the remote control inputs.

MacBook Air 11" Early 2015: Cause of shutdown when sleeping

Thu, 16 Apr 2026 04:52:10 -0700

What would cause this unit to shutdown after around 20 minutes when put to sleep? We haven't changed any battery or sleep mode settings and the battery is a good one. We can close the lid and open it after a few minutes and all is well, but when it is left closed for say 20 minutes the unit is turned off. We tested it with our clean installed SSD and the same happens..... We have reset the SMC, PRAM, run diagnostics & there are no errors being reported, ..... I have been told this was an issue with Monterey & up, but I never encountered this before....I noticed that when it is connected to a charger it didn't shut down after the lid is closed for a longer time. System is on 12.7.6.....baffled.

Galaxy S20: Microphone HS and Charging usb C/usb A doesn't work - SAMSUNG S20 5G

Thu, 16 Apr 2026 04:10:07 -0700

Hi everyone,

About a week ago, my Samsung S20 5G started having issues — it stopped charging with USB-C to USB-C. So I first tried cleaning the USB port, but that didn’t fix it.

A few days later, I also lost mic 1 (the one used for calls).

I then bought and replaced the charging port (daughterboard) without too much trouble, but the issue is still the same after reboot.

Right now:

it charges with USB-A to USB-C
but not with USB-C to USB-C

And now I’m getting a red temperature warning triangle, which even prevents charging with USB-A.

For context, my back cover is cracked, just in case that matters.

I’m running out of ideas at this point, so if anyone has suggestions, I’d really appreciate it!

Thanks in advance to anyone who tries to help! 🙏

iMac Intel 21.5" EMC 2428: iMac 2011 only #4 diagnostic LED is lit problem after upgrade

Thu, 16 Apr 2026 04:03:21 -0700

Hi everyone, I am kind of new here so here is my little story which I am having at the moment.
I have been diagnosing my iMac 21 mid 2011 for about a month, and I cannot get it to start back up no matter anything that I've tried and diagnosed, I only get #4 diagnostic LED to lit which is for LCD panel/inverter, nothing else.

First I thought it was the PSU on it's way to failure from age, but purchasing a new replacement didn't made any difference.

Then I've thought the internal connector which goes from power supply to the mb (motherboard) which gives it power and it may have been damaged while I disconnected it from the PSU, and I may have to get it, nothing changed.
But, one interesting thing is that both PSU's giving high pitched noise and "clicks" one or 2 per 3 seconds or so. I can record it as a voice memo if needed.
After that I thought the iMac's chassis may shorting components inside, so I measured voltages with the beeper on multi, everything is fine on that side. (no beeps)

As motherboards rarely fail, I also purchased a replacement, which also did no difference.

I think I have verified everything that could come to my mind, and I simply cannot get it power on no matter what I have tried. I am mostly specialist in laptops, so this is my first attempt and experience on getting inside an iMac.
I really hate throwing electronics away, I always try to diagnose them in every possible way. I have no one to ask and who could assist me in helping with this, as everyone who I know are always with their stuff.

If any more info is needed or I may have something missed during diagnostics, please please let me know, I will very much appreciate it.

PlayStation 4 Pro: PS4 Pro Displays Black Screen, Even in Safe Mode

Thu, 16 Apr 2026 04:02:05 -0700

Hello, I have a PS4 Pro CUH 7016B, and it has some strange issues. When I got the PS4, it would turn off after some time while playing demanding games, and it also had an overheating warning, so I thought new thermal paste would solve it. I used Arctic MX-6, and I am sure I applied it correctly, as I have done this many times. After reassembling the console, it was still not that quiet, but as far as I know, this is normal for Pros. The next day, I tried testing it further to ensure it was working properly, and in the middle of the game, it beeped three times and turned off. The weird thing is that the fans were not even at max speed, so I am assuming overheating is not an issue. I did not receive any overheating warnings. Sometimes it would also turn off without even beeping. To be completely sure, I reapplied the thermal paste, but that did not change anything. Then I tried testing the PSU with a multimeter, and it was showing 11.86 volts, so that should be okay. The next thing I tried was replacing the HDD, but after doing so, the blue light would flash once before the console turned off. After trying to power it on a few more times, it turned on, but now all I see is a black image, and that's it. I tried putting the old HDD back in, but nothing changed. The same thing happened in safe mode. I also tried cleaning the HDMI cord, using different TVs and displays, and using a different HDMI cable, all with no success. Does anybody know why this is happening? Maybe my APU is dead?

Edit: i should have clarified this before but it does actually seem to enter safe mode because the light turns white.

Miele w3740 honeycomb: Miele W3740 - F97 error persists after reset and drum light check

Thu, 16 Apr 2026 03:05:22 -0700

Hello, my Miele W3740 washing machine is showing the F97 error code. I have already performed the following troubleshooting steps:

Checked for a drum light bulb: My specific sub-model does not seem to have one, but I found the orange tool behind the detergent drawer.
Attempted a power reset: I left the machine unplugged for over 20 minutes, but the error returns immediately upon power-up.
Tried entering the service menu: The error F97 is persistent and blocks access to the standard reset procedures.

The machine is currently disassembled. I suspect a hardware failure on the Main Power Electronic Module (ELP). Does anyone know which specific components (relays, capacitors, or transistors) typically fail on the ELP board when this error occurs? Are there any specific test points I should check with a multimeter?

Thank you for any technical advice!`
